He needs to follow the order of operations.
He needs to reverse the order of operations.
8 is attached to 3 n by subtraction.
8 is the first term in the equation.
The correct answer is: 8 is attached to 3n by subtraction.
By subtracting 8 from both sides of the equation, Jonny is isolating the variable (n) on one side of the equation. This step allows him to solve for n by dividing both sides by 3.
